Grades
I'm a CCN 3L who accepted an offer at the v5 firm I want to stay at until they stealthily lay me off. What's the minimum amount of time I need to be at the firm until the lower ranked firm or in house I lateral to doesn't care about a huge grade drop?

You sound like a douchebag with a small cock. If you're a woman, you are a fat hooker.

I want to know too: how long before grades are not important anymore? (If you got into a V5 despite mediocre grades.)
575,800 minutes
3:00 - that's 400 years.
It's actually 400 days.
575,800/60 minutes/24 hours = 400 days
I'd like to know too. I'm in the same situation.
note to OP, grades all fudged. See post about NYU grades, USC grades, harvard's non-grades, Stanford's non-grades, etc.
The slow ones finally get it . . . finally. Grades don't mean much. You live in a post-modernist, post-grade society. get used to it.
But how does it work? Say you have a 3.2 from Cornell and through some combination of luck, relevant work experience and interview skills you land a job at Cravath. At what point does the fact that you worked at Cravath become more important than the 3.2?
Say you want to lateral after two or three years at the firm, how well will you do compared to other Cravath associates, who got in with better grades from better schools?
Grades reflect potential, experience describes reality. The key factor after your first year at V5 is the kind and quality of work you actually do. Given your admission that you're lazy, I wouldn't hold my breath for offers after a year at V5. After two years of solid work though, you shouldn't have any troubles.
Yo 1, how about some naked armwrestling? I think you'd like it... call me.
I wouldn't hire you.

I'm a 2L at a Top 20 law school, and I I have a B+ average. I took an exam last week that went horribly. The course is known to be tough and is not in my area of interest. Will my summer firm ding me based on one grade?
If they ding you, it won't be because of one grade.
@OP: With your attitude, sucks to be the V5 firm that made an offer to you. And you brag about it on ATL? Nice. Let's hope your firm doesn't figure out who you are from your writing style.
Life is not a formula. Go live a little and make decisions as they come.
how many CCN 3Ls at V5's with grade drops can there be?
Please don't be so specific with your details.
